TECHNICAL FIELD

The technical field relates to agents for hair treatment containing a combination of at least one special amphiphilic cationic polymer with at least one special copolymer, to the use of said agents for the temporary deformation and/or care of keratin-containing fibers, and to aerosol hair sprays/foams based on said agents.

BACKGROUND

“Keratinic fibers” are understood in principle as all animal hairs, e.g. wool, horsehair, angora hair, furs, feathers, and products or textiles produced therefrom. Preferably, however, the keratinic fibers are human hairs.

An attractive-looking hairstyle is generally regarded these days as an indispensable element of a well-groomed appearance. Given the currents of fashion, more and more hairstyles regarded as chic are ones that, for many types of hair, can be constructed, or maintained for a longer period of time of up to several days, only with the use of setting active agents. Hair treatment agents that serve for permanent or temporary shaping of the hair therefore play an important role. Temporary shaping results that are intended to result in good hold without impairing the healthy appearance of the hair, for example its shine, can be achieved e.g. using hair sprays, hair waxes, hair gels, hair foams, blow-dry waves, etc.

Corresponding agents for temporary shaping usually contain synthetic polymers as a shaping component. Preparations that contain a dissolved or dispersed polymer can be applied onto the hair by means of propellant gases or using a pump mechanism. Hair gels and hair waxes in particular, however, are as a rule not applied directly onto the hair but instead are distributed in the hair using a comb or the hands.

The most important property of an agent for the temporary deformation of keratinic fibers, hereinafter also called a “styling agent,” is to impart the strongest possible hold to the treated fibers in the shape that is generated. If the keratinic fibers involved are human hairs, terms also used are a strong “hairstyle hold” or a high “degree of hold” of the styling agent. The hairstyle hold is determined substantially by the nature and quantity of the setting polymer used, although the further constituents of the styling agent can also have an influence.

In addition to a high degree of hold, styling agents must meet a large number of further requirements. These can be subdivided roughly into: properties on the hair; properties of the particular formulation, e.g. properties of the foam, gel, or sprayed aerosol; and properties that relate to the handling of the styling agent, the properties on the hair being of particular importance. Moisture resistance, low tack, and a balanced conditioning effect may be mentioned in particular. In addition, a styling agent should be universally usable for, if possible, all types of hair.

A plurality of synthetic polymers that are utilized in styling agents have already been developed in order to meet the various requirements. The polymers can be subdivided into cationic, anionic, nonionic, and amphoteric film-forming and/or setting polymers. Ideally, upon application onto the hair the polymers yield a polymer film that on the one hand imparts a strong hold to the hairstyle but on the other hand is sufficiently flexible not to break under stress. If the polymer film is too brittle, this results in the formation of so-called “film plaques,” i.e. residues that detach as the hair moves and give the impression that the user of the corresponding styling agent has dandruff.

It is still difficult to develop styling agents that exhibit all desired properties in combination. This is true in particular for the combination of strong hold on the one hand, and simple, uniform application onto the keratin-containing fibers on the other hand.

SUMMARY

A cosmetic agent for cosmetic treatment of keratin-containing fibers is provided which comprises: a cosmetically acceptable carrier; and (a) at least one amphiphilic cationic polymer comprising at least one structural unit of formula (I), at least one structural unit of formula (II), at least one structural unit of formula (III), and at least one structural unit of formula (IV),

in which R¹ and R⁴ mutually independently denote a hydrogen atom or a methyl group, X¹ and X² mutually independently denote an oxygen atom or an NH group, A¹ and A² mutually independently denote an ethane-1,2-diyl group, propane-1,3-diyl group, or butane-1,4-diyl group, R², R³, R⁵, and R⁶ mutually independently denote a (C₁ to C₄) alkyl group, R⁷ denotes a (C₈ to C₃₀) alkyl group; and

(b) at least one copolymer comprising at least one structural unit of formula (A1), at least one structural unit of formula (A2), and at least one structural unit of formula (A3),

in which R¹, R³, and R⁷ mutually independently denote a hydrogen atom or a methyl group, R² denotes a (C₁ to C₄) alkyl group, and R⁴ denotes a hydroxy-(C₂ to C₆) alkyl group.

A method is also provided, for treating keratin-containing fibers, in which the foregoing agent is foamed into a foam with the use of a delivery apparatus, and the resulting foam is applied onto the keratin-containing fibers.

DETAILED DESCRIPTION

The object was therefore to furnish an agent for the temporary deformation and/or care of keratinic fibers that is notable for a high degree of hold and for a good care-providing effect, and in particular possesses outstanding ease of handling during application onto the keratinic fibers.

It has now been found, surprisingly, that this can be achieved by way of a combination of special polymers. It has furthermore been possible in the context of special embodiments of the agents described herein to provide, in addition to these outstanding properties, compositions having no turbidity. Freedom from turbidity matters in particular in the context of the provision of aerosol compositions, since solid suspended particles can result in clogging of the exit nozzle of the aerosol package. In the case of turbid and low-viscosity compositions a general risk of sedimentation additionally exists, which has a disadvantageous effect on the shelf stability of the composition.

-   -   addition products of about 2 to about 100 mol ethylene oxide         and/or about 1 to about 5 mol propylene oxide with linear and         branched fatty alcohols having 8 to 30 carbon atoms, with fatty         acids having 8 to 30 carbon atoms, and with alkylphenols having         8 to 15 carbon atoms in the alkyl group,     -   addition products, end-capped with a methyl residue or C₂ to C₆         alkyl residue, of about 2 to about 50 mol ethylene oxide and/or         about 1 to about 5 mol propylene oxide with linear and branched         fatty alcohols having 8 to 30 carbon atoms, with fatty acids         having 8 to 30 carbon atoms, and with alkylphenols having 8 to         15 carbon atoms in the alkyl group, for example the grades         obtainable under the marketing designations Dehydrol® LS,         Dehydrol® LT (Cognis),     -   C₁₂ to C₃₀ fatty acid mono- and diesters of addition products of         about 1 to about 30 mol ethylene oxide with glycerol,     -   addition products of about 5 to about 60 mol ethylene oxide with         castor oil and hardened castor oil,     -   polyol fatty acid esters, for example the commercial product         Hydagen® HSP (Cognis), or Sovermol grades (Cognis),     -   alkoxylated triglycerides,     -   alkoxylated fatty acid alkyl esters of formula (E4-I)         R¹CO—(OCH₂CHR²)_(w)OR³  (E4-I),     -   in which R¹CO denotes a linear or branched, saturated and/or         unsaturated acyl residue having 6 to 22 carbon atoms, R² denotes         hydrogen or methyl, R³ denotes linear or branched alkyl residues         having 1 to 4 carbon atoms, and w denotes numbers from 1 to 20,     -   amine oxides,     -   hydroxy mixed ethers, for example as described in German         Application 19738866,     -   sorbitan fatty acid esters and addition products of ethylene         oxide with sorbitan fatty acid esters, for example polysorbates,     -   sugar fatty acid esters and addition products of ethylene oxide         with sugar fatty acid esters,     -   addition products of ethylene oxide with fatty acid         alkanolamides and fatty amines,     -   sugar surfactants of the alkyl and alkenyl oligoglycoside types,         in accordance with formula (E4-II)         R⁴O-[G]_(p)  (E4-II)     -   in which R⁴ denotes an alkyl or alkenyl residue having 4 to 22         carbon atoms, G denotes a sugar residue having 5 or 6 carbon         atoms, and p denotes numbers from 1 to 10. They can be obtained         using the relevant methods of preparative organic chemistry.

Alkylene oxide addition products with saturated linear fatty alcohols and fatty acids, having respectively about 2 to about 100 mol ethylene oxide per mol of fatty alcohol or fatty acid, have proven to be very particularly preferred nonionic surfactants. Preparations having outstanding properties are likewise obtained when they contain C₁₂ to C₃₀ fatty acid mono- and diesters of addition products of about 1 to about 30 mol ethylene oxide with glycerol, and/or addition products of about 5 to about 60 mol ethylene oxide with castor oil and hardened castor oil, as nonionic surfactants.

Cationic surfactants of the quaternary ammonium compound, esterquat, and amidoamine types are also usable. Preferred quaternary ammonium compounds are ammonium halides, in particular chlorides and bromides, such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides, and trialkylmethylammonium chlorides. The long alkyl chains of these surfactants preferably have 10 to 18 carbon atoms, for example as in cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride, and tricetylmethylammonium chloride.

“Zwitterionic surfactants” refers to those surface-active compounds which carry in the molecule at least one quaternary ammonium group and at least one —COO⁽⁻⁾ or SO₃ ⁽⁻⁾ group. Particularly suitable zwitterionic surfactants are the so-called betaines, such as N-alkyl-N,N-dimethylammonium glycinates, for example cocalkyldimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinates, for example cocacylaminopropyldimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines, having in each case 8 to 18 carbon atoms in the alkyl or acyl group, as well as cocacylaminoethylhydroxyethylcarboxymethyl glycinate. A preferred zwitterionic surfactant is the fatty acid amide derivative known by the INCI name Cocamidopropyl Betaine.

“Ampholytes” are understood to be those surface-active compounds which contain in the molecule, besides a C₈ to C₂₄ alkyl or acyl group, at least one free amino group and at least one —COOH or —SO₃H group, and are capable of forming internal salts. Examples of suitable ampholytes are N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids, and alkylaminoacetic acids, having in each case approximately 8 to 24 carbon atoms in the alkyl group. Particularly preferred ampholytes are N-cocalkylaminopropionate, cocacylaminoethylaminopropionate, and C₁₂ to C₁₈ acyl sarcosine.

The agents contemplated herein contain the ingredients or active agents in a cosmetically acceptable carrier.

Preferred cosmetically acceptable carriers are aqueous, alcoholic, or aqueous alcoholic media having preferably at least about 10 wt % water, based on the total agent. The alcohols contained can be, in particular, the lower alcohols having 1 to 4 carbon atoms usually used for cosmetic purposes, for example ethanol and isopropanol.

It is preferred according to use at least one (C₁ to C₄) monoalkyl alcohol in the agents, in particular in a quantity from about 1 to about 50 wt %, in particular from about 5 to about 30 wt %. This is in turn preferred in particular for packaging as a pump foam or aerosol foam.

Organic solvents or a mixture of solvents having a boiling point below about 400° C. can be contained as additional co-solvents, in a quantity from about 0.1 to about 15 weight percent, preferably from about 1 to about 10 weight percent, based on the total agent. Unbranched or branched hydrocarbons such as pentane, hexane, isopentane, and cyclic hydrocarbons such as cyclopentane and cyclohexane, are particularly suitable as additional co-solvents. Further particularly preferred water-soluble solvents are glycerol, ethylene glycol, and propylene glycol, in a quantity of up to about 30 wt % based on the total agent.

The addition in particular of glycerol and/or propylene glycol and/or polyethylene glycol and/or polypropylene glycol increases the flexibility of the polymer film formed when the agent described herein is utilized. If a flexible hold is desired, the agents therefore preferably contain about 0.01 to about 30 wt % glycerol and/or propylene glycol and/or polyethylene glycol and/or polypropylene glycol, based on the total agent.

The agents preferably have a pH from about 2 to about 11. The pH range between about 2 and about 8 is particularly preferred. Unless otherwise noted, indications as to pH refer, for purposes of this document, to the pH at 25° C.

The agents can furthermore contain the adjuvants and additives that are usually added to conventional styling agents.

Additional care-providing substances are to be recited in particular as additional adjuvants and additives.

A silicone oil and/or a silicone gum can be used, for example, as a care-providing substance.

Suitable silicone oils or silicone gums are, in particular, dialkyl- and alkylarylsiloxanes, for example dimethylpolysiloxane and methylphenylpolysiloxane, as well as alkoxylated, quaternized, or also anionic derivatives thereof. Cyclic and linear polydialkylsiloxanes, alkoxylated and/or aminated derivatives thereof, dihydroxypolydimethylsiloxanes, and polyphenylalkylsiloxanes are preferred.

Silicone oils produce a wide variety of effects. For example, they simultaneously influence dry and wet compatibility, the feel of the dry and wet hair, and shine. The skilled artisan understands the term “silicone oils” as several structures of organosilicon compounds. It is understood firstly as dimethiconols.

The following commercial products are recited as examples of such products: Botanisil NU-150M (Botanigenics), Dow Corning 1-1254 Fluid, Dow Corning 2-9023 Fluid, Dow Corning 2-9026 Fluid, Ultrapure Dimethiconol (Ultra Chemical), Unisil SF-R (Universal Preserve), X-21-5619 (Shin-Etsu Chemical Co.), Abil OSW 5 (Degussa Care Specialties), ACC DL-9430 Emulsion (Taylor Chemical Company), AEC Dimethiconol & Sodium Dodecylbenzenesulfonate (A & E Connock (Perfumery & Cosmetics) Ltd.), B C Dimethiconol Emulsion 95 (Basildon Chemical Company, Ltd.), Cosmetic Fluid 1401, Cosmetic Fluid 1403, Cosmetic Fluid 1501, Cosmetic Fluid 1401DC (all the aforesaid Chemsil Silicones, Inc.), Dow Corning 1401 Fluid, Dow Corning 1403 Fluid, Dow Corning 1501 Fluid, Dow Corning 1784 HVF Emulsion, Dow Corning 9546 Silicone Elastomer Blend (all the aforesaid Dow Corning Corporation), Dub Gel SI 1400 (Stearinerie Dubois FiIs), HVM 4852 Emulsion (Crompton Corporation), Jeesilc 6056 (Jeen International Corporation), Lubrasil, Lubrasil DS (both Guardian Laboratories), Nonychosine E, Nonychosine V (both Exsymol), SanSurf Petrolatum-25, Satin Finish (both Collaborative Laboratories, Inc.), Silatex-D30 (Cosmetic Ingredient Resources), Silsoft 148, Silsoft E-50, Silsoft E-623 (all the aforesaid Crompton Corporation), SM555, SM2725, SM2765, SM2785 (all the aforesaid GE Silicones), Taylor T-SiI CD-1, Taylor TME-4050E (all Taylor Chemical Company), TH V 148 (Crompton Corporation), Tixogel CYD-1429 (Sud-Chemie Performance Additives), Wacker-Belsil CM 1000, Wacker-Belsil CM 3092, Wacker-Belsil CM 5040, Wacker-Belsil DM 3096, Wacker-Belsil DM 3112 VP, Wacker-Belsil DM 8005 VP, Wacker-Belsil DM 60081 VP (all the aforesaid Wacker-Chemie GmbH).

Dimethicones constitute the second group of silicones that can be contained in the agents described herein. They can be both linear and branched, and also cyclic or cyclic and branched.

Dimethicone copolyols (S3) constitute a further group of silicones that are suitable. Corresponding dimethicone copolyols are commercially obtainable and are marketed, for example, by the Dow Corning company under the designation Dow Corning® 5330 Fluid.

The description provided herein, of course, encompasses the fact that dimethiconols, dimethicones, and/or dimethicone copolymers can already be present in the agents as an emulsion. The corresponding emulsion of dimethiconols, dimethicones, and/or dimethicone copolyols can be produced both after manufacture of the corresponding dimethiconols, dimethicones, and/or dimethicone copolyols, from them and using usual emulsification methods known to one skilled in the art. For this purpose both cationic, anionic, nonionic, or zwitterionic surfactants and emulsifier agents can be used, as auxiliaries, as adjuvants for manufacture of the corresponding emulsions. The emulsions of dimethiconols, dimethicones, and/or dimethicone copolyols can of course also be manufactured directly by way of an emulsion polymerization method. Such methods, too, are very familiar to one skilled in the art.

If dimethiconols, dimethicones, and/or dimethicone copolyols are used as an emulsion, then the droplet size of the emulsified particles is equal to about 0.01 to about 10,000 μm, preferably about 0.01 to about 100 μm, particularly preferably about 0.01 to about 20 μm, and very particularly preferably about 0.01 to about 10 μm. The particle size is determined using the light-scattering method.

When “branched” dimethiconols, dimethicones, and/or dimethicone copolyols are used, this is to be understood to mean that the branching is greater than a random branching that occurs randomly as a result of impurities in the respective monomers. The term “branched” as used herein to describe dimethiconols, dimethicones, and/or dimethicone copolyols means that the degree of branching is greater than about 0.01%. A degree of branching greater than about 0.1% is preferred, and very particularly preferably it is greater than about 0.5%. The degree of branching is determined from the ratio of unbranched monomers to the branching monomers, i.e. to the quantity of tri- and tetrafunctional siloxanes. Both low-branching and high-branching dimethiconols, dimethicones, and/or dimethicone copolyols can be very particularly preferred.

Particularly suitable silicones are aminofunctional silicones, in particular the silicones grouped under the INCI name Amodimethicone. It is therefore preferred that the agents additionally contain at least one aminofunctional silicone. These are to be understood as silicones that comprise at least one optionally substituted amino group. These silicones are referred to according to the INCI declaration as Amodimethicone, and are obtainable, for example, in the form of an emulsion as a commercial product Dow Corning® 939, or as a commercial product Dow Corning® 949, mixed with a cationic and a nonionic surfactant.

Those aminofunctional silicones which have an amine number above about 0.25 meq/g, preferably above about 0.3 meq/g, and particularly preferably above about 0.4 meq/g are preferably used. The amine number here denotes the milliequivalent of amine per gram of the aminofunctional silicone; it can be ascertained by titration, and can also be indicated with the “mg KOH/g” unit.

The agents contain silicones preferably in quantities from about 0.01 wt % to about 15 wt %, particularly preferably from about 0.05 to about 2 wt %, based on the total agent.

The agent can, for example, contain at least one protein hydrolysate and/or one of its derivatives as a care-providing substance of a different class of compound.

Protein hydrolysates are product mixtures obtained by the acid-, base-, or enzyme-catalyzed breakdown of proteins. The term “protein hydrolysates” as used herein is also understood to mean total hydrolysates as well as individual amino acids and derivatives thereof, as well as mixtures of different amino acids. The molecular weight of the protein hydrolysates usable is between about 75 (the molecular weight of glycine) and about 200,000; the molecular weight is preferably equal to about 75 to about 50,000, and very particularly preferably to about 75 to about 20,000 dalton.

Protein hydrolysates of both vegetable as well as animal or marine or synthetic origin can be used in the agents described herein.

Animal protein hydrolysates are, for example, protein hydrolysates of elastin, collagen, keratin, silk, and milk protein, which can also be present in the form of salts. Such products are marketed, for example, under the trademarks Dehylan® (Cognis), Promois® (Interorgana), Collapuron® (Cognis), Nutrilan® (Cognis), Gelita-Sol® (Deutsche Gelatine Fabriken Stoess & Co), Lexein® (Inolex), Sericin (Pentapharm), and Kerasol® (Croda).

Protein hydrolysates are contained in the agents, for example, in concentrations from about 0.01 wt % to about 20 wt %, preferably from about 0.05 wt % to about 15 wt %, and very particularly preferably in quantities from about 0.05 wt % to about 5 wt %, based in each case on the total utilization preparation.

The agent can further contain at least one vitamin, one provitamin, one vitamin precursor, and/or one derivative thereof as a care-providing substance.

Those vitamins, provitamins, and vitamin precursors which are usually assigned to the groups A, B, C, E, F, and H are preferred.

The group of substances referred to as “vitamin A” includes retinol (vitamin A₁) as well as 3,4-didehydroretinol (vitamin A₂). β-Carotene is the provitamin of retinol. Vitamin A components that are suitable include, for example, vitamin A acid and esters thereof, vitamin A aldehyde, and vitamin A alcohol, as well as esters thereof such as the palmitate and acetate. The agents contain the vitamin A component preferably in quantities from about 0.05 to about 1 wt %, based on the total utilization preparation.

Members of the vitamin B group or vitamin B complex are, among others, vitamin B₁ (thiamine), vitamin B₂ (riboflavin), vitamin B₃ (nicotinic acid and/or nicotinic acid amide (niacinamide)), vitamin B₅ (pantothenic acid, panthenol, and pantolactone), vitamin B₆ (pyridoxine as well as pyridoxamine and pyridoxal), vitamin C (ascorbic acid), vitamin E (tocopherols, in particular α-tocopherol), vitamin F (linoleic acid and/or linolenic acid), vitamin H.

The agents contemplated herein preferably contain vitamins, provitamins, and vitamin precursors from the groups A, B, C, E, and H. Panthenol, pantolactone, and pyridoxine and derivatives thereof, as well as nicotinic acid amide and biotin, are particularly preferred.

D-Panthenol is very particularly preferred as a care-providing substance, optionally in combination with at least one of the silicone derivatives recited above.

Like the addition of glycerol and/or propylene glycol, the addition of panthenol increases the flexibility of the polymer film formed upon utilization of the agent. If a particularly flexible hold is desired, the agents can thus contain panthenol instead of or in addition to glycerol and/or propylene glycol. In a preferred embodiment the agents contain panthenol, preferably in a quantity from about 0.05 to about 10 wt %, particularly preferably about 0.1 to about 5 wt %, based in each case on the total agent.

The agents described herein can furthermore contain at least one plant extract as a care-providing substance.

These extracts are usually produced by extraction of the entire plant. In individual cases, however, it may also be preferred to produce the extracts exclusively from blossoms and/or from leaves of the plant.

Extracts from green tea, oak bark, nettle, witch hazel, hops, henna, chamomile, burdock root, horsetail, hawthorn, linden blossoms, almond, aloe vera, pine needles, horse chestnut, sandalwood, juniper, coconut, mango, apricot, lemon, wheat, kiwi fruit, melon, orange, grapefruit, salvia, rosemary, birch, mallow, lady's-smock, wild thyme, yarrow, thyme, lemon balm, restharrow, coltsfoot, hibiscus, meristem, ginseng, and ginger root are especially preferred.

It can further be preferred to use in the agents mixtures of several, in particular of two, different plant extracts.

Mono- or oligosaccharides can also be used as a care-providing substance in the agents.

Both monosaccharides and oligosaccharides, for example cane sugar, milk sugar, and raffinose, can be used. The use of monosaccharides is preferred. Among the monosaccharides, those compounds which contain 5 or 6 carbon atoms are in turn preferred.

Suitable pentoses and hexoses are, for example, ribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose, talose, fucose and fructose. Arabinose, glucose, galactose and fructose are carbohydrates that are preferably used; it is very particularly preferred to use glucose, which is suitable both in the D-(+) or L-(−) configuration or as a racemate. Derivatives of these pentoses and hexoses, such as the corresponding -onic and -uronic acids (sugar acids), sugar alcohols, and glycosides, can also be used. Preferred sugar acids are gluconic acid, glucuronic acid, saccharic acid, mannosaccharic acid, and mucic acid. Preferred sugar alcohols are sorbitol, mannitol, and dulcitol. Preferred glycosides are methyl glucosides.

Because the mono- or oligosaccharides that are used are usually obtained from natural raw materials such as starch, as a rule they exhibit the configurations corresponding to those raw materials (e.g. D-glucose, D-fructose and D-galactose).

Mono- or oligosaccharides are contained in the agents preferably in a quantity from about 0.1 to about 8 wt %, particularly preferably from about 1 to about 5 wt %, based on the total utilization preparation.

The agent can furthermore contain at least one lipid as a care-providing substance.

Lipids suitable for use in the agents described herein are phospholipids, for example soy lecithin, egg lecithin, and kephalins, as well as the substances known by the INCI names Linoleamidopropyl PG-Dimonium Chloride Phosphate, Cocamidopropyl PG-Dimonium Chloride Phosphate, and Stearamidopropyl PG-Dimonium Chloride Phosphate. These are marketed, for example, by the Mona company under the commercial designations Phospholipid EFA®, Phospholipid PTC®, and Phospholipid SV®. The agents contain lipids preferably in quantities from about 0.01 to about 10 wt %, in particular about 0.1 to about 5 wt %, based on the total utilization preparation.

Oleic acid monoglycerides are         preferably used.

The quantity of natural and synthetic cosmetic oily substances used in the agents is usually about 0.1 to about 30 wt %, based on the total utilization preparation, preferably about 0.1 to about 20 wt %, and in particular about 0.1 to about 15 wt %.

Although each of the aforesaid care-providing substances by itself already provides a satisfactory result, all embodiments in which the agent contains multiple care-providing substances, including from different groups, are also contemplated.

The addition of a UV filter allows both the agents themselves, and the treated fibers, to be protected from damaging influences of UV radiation. At least one UV filter is therefore preferably added to the agent. The suitable UV filters are not subject to any general restrictions in terms of their structure and their physical properties. Instead, all UV filters usable in the cosmetics sector, whose absorption maximum lies in the UVA (315 to 400 nm) UVB (280 to 315 nm), or UVC (<280 nm) regions, are suitable. UV filters having an absorption maximum in the UVB region, in particular in the region from approximately 280 to approximately 300 nm, are particularly preferred.

Preferred UV filterscan be selected, for example, from substituted benzophenones, p-aminobenzoic acid esters, diphenylacrylic acid esters, cinnamic acid esters, salicylic acid esters, benzimidazoles, and o-aminobenzoic acid esters.

Examples of usable UV filters are 4-aminobenzoic acid, N,N,N-trimethyl-4-(2-oxoborn-3-ylidenemethyl)aniline methylsulfate, 3,3,5-trimethylcyclohexyl salicylate (Homosalate), 2-hydroxy-4-methoxybenzophenone, 2-phenylbenzimidazole-5-sulfonic acid and potassium, sodium, and triethanolamine salts thereof, 3,3′-(1,4-phenylenedimethylene)-bis(7,7-dimethyl-2-oxobicyclo-[2.2.1]hept-1-yl-methanesulfonic acid) and salts thereof, 1-(4-tert-butylphenyl)-3-(4-methoxyphenyl)propane-1,3-dione, α-(2-oxoborn-3-ylidene)toluene-4-sulfonic acid and salts thereof, ethoxylated 4-aminobenzoic acid ethyl ester (PEG-25 PABA; Uvinul®P 25), 4-dimethylaminobenzoic acid 2-ethylhexyl ester, salicylic acid 2-ethylhexyl ester, 4-methoxycinnamic acid isopentyl ester, 4-methoxycinnamic acid 2-ethylhexyl ester, 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and the sodium salt thereof (Benzophenone-4; Uvinul® MS 40; Uvasorb® S 5), 3-(4′-methylbenzylidene) D,L-camphor, 3-benzylidene camphor (3-Benzylidene Camphor), 4-isopropylbenzyl salicylate, 2,4,6-trianilino-(p-carbo-2′-ethylhexyl-1′-oxy)-1,3,5-triazine, 3-imidazol-4-ylacrylic acid and ethyl esters thereof, polymers of N-{(2 and 4)[2-oxoborn-3-ylidenemethyl]benzyl}acrylamide, 2,4-dihydroxybenzophenone, 1,1′-diphenylacrylonitrilic acid 2-ethylhexyl ester, o-aminobenzoic acid menthyl ester, 2,2′,4,4′-tetrahydroxybenzophenone, 2,2′-dihydroxy-4,4′-dimethoxybenzophenone, 2,2′-dihydroxy-4,4′-dimethoxybenzophenone-5-sodiumsulfonate, and 2-cyano-3,3-diphenylacrylic acid 2′-ethylhexyl ester. 2-Hydroxy-4-methoxybenzophenone-5-sulfonic acid and the sodium salt thereof, and/or ethoxylated 4-aminobenzoic acid ethyl ester, are preferred.

UV filters are contained usually in quantities from about 0.01 to about 5 wt %, based on the total utilization preparation. Quantities from about 0.1 to about 2.5 wt % are preferred.

In a particular embodiment, the agent furthermore contains one or more substantive dyes. This allows the keratinic fibers treated upon use of the agent to be not only temporarily structured, but at the same time also dyed. This can be desirable in particular when what is desired is only a temporary coloration, for example with conspicuous “fashion” colors, which can be removed again from the keratinic fibers simply by washing.

Substantive dyes are usually nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, or indophenols. Preferred substantive dyes are the compounds known by the international designations or trade names HC Yellow 2, HC Yellow 4, HC Yellow 5, HC Yellow 6, HC Yellow 12, Acid Yellow 1, Acid Yellow 10, Acid Yellow 23, Acid Yellow 36, HC Orange 1, Disperse Orange 3, Acid Orange 7, HC Red 1, HC Red 3, HC Red 10, HC Red 11, HC Red 13, Acid Red 33, Acid Red 52, HC Red BN, Pigment Red 57:1, HC Blue 2, HC Blue 11, HC Blue 12, Disperse Blue 3, Acid Blue 7, Acid Green 50, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Acid Violet 43, Disperse Black 9, Acid Black 1, and Acid Black 52, as well as 1,4-diamino-2-nitrobenzene, 2-amino-4-nitrophenol, 1,4-bis-(β-hydroxyethyl)amino-2-nitrobenzene, 3-nitro-4-(β-hydroxyethyl)aminophenol, 2-(2′-hydroxyethyl)amino-4,6-dinitrophenol, 1-(2′-hydroxyethyl)amino-4-methyl-2-nitrobenzene, 1-amino-4-(2′-hydroxyethyl)amino-5-chloro-2-nitrobenzene, 4-amino-3-nitrophenol, 1-(2′-ureidoethyl)amino-4-nitrobenzene, 4-amino-2-nitrodiphenylamine-2′-carboxylic acid, 6-nitro-1,2,3,4-tetrahydroquinoxaline, 2-hydroxy-1,4-naphthoquinone, picramic acid and salts thereof, 2-amino-6-chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid, and 2-chloro-6-ethylamino-1-hydroxy-4-nitrobenzene. It is preferred to use cationic substantive dyes. Particularly preferred in this context are

-   (a) cationic triphenylmethane dyes, for example Basic Blue 7, Basic     Blue 26, Basic Violet 2, and Basic Violet 14; -   (b) aromatic systems that are substituted with a quaternary nitrogen     group, for example Basic Yellow 57, Basic Red 76, Basic Blue 99,     Basic Brown 16, and Basic Brown 17; and -   (c) substantive dyes that contain a heterocycle which comprises at     least one quaternary nitrogen atom, such as those recited, for     example, in claims 6 to 11 of EP-A2-998 908, to which reference is     explicitly made at this juncture.

The dyes also known by the designations Basic Yellow 87, Basic Orange 31, and Basic Red 51 are very particularly preferred cationic substantive dyes of group (c). The cationic substantive dyes that are marketed under the trademark Arianor® are likewise cationic substantive dyes very particularly preferred.

In such an embodiment, the agents contain substantive dyes preferably in a quantity from about 0.001 to about 20 wt %, based on the total agent.

It is preferred that the agents be free of oxidation dye precursors. Oxidation dye precursors are divided into so-called developer components and coupler components. The developer components form the actual dyes, under the influence of oxidizing agents or atmospheric oxygen, with one another or by coupling with one or more coupler components.

The agents can be formulated in any form usual for styling agents, for example in the form of solutions that can be applied onto the hair as a hair lotion or as a pump spray or aerosol spray, in the form of creams, emulsions, waxes, gels, or also surfactant-containing foaming solutions or other preparations that are suitable for application to the hair.

Hair creams and hair gels generally contain structuring agents and/or thickening polymers which serve to impart the desired consistency to the products. Structuring agents and/or thickening polymers are used typically in a quantity from about 0.1 to about 10 wt %, based on the total product. Quantities from about 0.5 to about 5 wt %, in particular about 0.5 to about 3 wt %, are preferred.

The agents are preferably packaged as a pump spray, aerosol spray, pump foam, or aerosol foam. For this, the agents are packaged in a delivery apparatus that represents either a pressurized-gas container additionally filled with a propellant (“aerosol container”) or a non-aerosol container.

The pressurized-gas containers with which a product is distributed through a valve as a result of the internal gas pressure of the container are referred to by definition as “aerosol containers.” A “non-aerosol container” is defined, conversely to the “aerosol” definition, as a vessel under standard pressure with which a product is distributed by means of mechanical action by way of a pump system.

The agents are packaged particularly preferably as an aerosol hair foam or aerosol hair spray. The agent (in particular the preferred embodiments (A) to (F)) (see above) therefore preferably additionally contains at least one propellant.

Propellants suitable for use with the agents described herein are selected, for example, from N₂O, dimethyl ether, CO₂, air, alkanes having 3 to 5 carbon atoms such as propane, n-butane, isobutane, n-pentane, and isopentane, and mixtures thereof. Dimethyl ether, propane, n-butane, isobutane, and mixtures thereof are preferred.

According to a preferred embodiment, the aforesaid alkanes, mixtures of the aforesaid alkanes, or mixtures of the aforesaid alkanes with dimethyl ether are used as the only propellant. The agents contemplated herein also expressly encompass, however, the concurrent use of propellants of the chlorofluorocarbon type, but in particular fluorocarbons.

For a given spray apparatus, the sizes of the respective aerosol droplets or foam bubbles, and the respective size distribution, can be adjusted by way of the quantitative ratio between the propellant and the other constituents of the preparations.

The quantity of propellant used varies as a function of the specific composition of the agent, the packaging used, and the desired type of product (e.g. hair spray or hair foam). When conventional spray apparatuses are used, aerosol foam products contain the propellant preferably in quantities from about 1 to about 35 wt %, based on the total product. Quantities from about 2 to about 30 wt %, in particular from about 3 to about 15 wt %, are particularly preferred. Aerosol sprays generally contain larger quantities of propellant. In this case the propellant is used preferably in a quantity from about 30 to about 98 wt %, based on the total product. Quantities from about 40 to about 95 wt %, in particular from about 50 to about 95 wt %, are particularly preferred.

The aerosol products can be manufactured in usual fashion. As a rule all the constituents of the particular agent, with the exception of the propellant, are introduced into a suitable pressure-tight container. The latter is then sealed with a valve. Lastly, the desired quantity of propellant is introduced using conventional techniques.

Isopentane is preferably suitable as a propellant for foaming gel-type agents in a two-chamber aerosol container, which propellant is incorporated into the agents and is packaged in the first chamber of the two-chamber aerosol container. Packaged in the second chamber of the two-chamber aerosol container is at least one further propellant, different from isopentane, that builds up in the two-chamber aerosol container a higher pressure than the isopentane. The propellants of the second chamber are preferably selected from N₂O, dimethyl ether, CO₂, air, alkanes having 3 or 4 carbon atoms (such as propane, n-butane, isobutane), and mixtures thereof.

A preferred embodiment of the agents described herein is aerosol hair foams or aerosol hair sprays containing the agent described previously, and at least one propellant.

Preferred agents and propellants of the aerosol hair foam or aerosol hair spray, as well as the respective quantities of propellant, correspond to the statements already made above.

A second subject of the agents contemplated herein is the use of the agents for the temporary deformation of hair and/or for hair care.

The agents, and products that contain these agents, in particular aerosol hair foams or aerosol hair sprays, are notable in particular for the fact that they impart a very strong, durable hairstyle hold to the treated hair, even though the hair remains flexible. If the agent is packaged as a hair foam, a stable, fine-pored, and creamy foam forms, which can be distributed onto the hair evenly and without dripping.

A third subject of the agents contemplated herein is a method for treating keratin-containing fibers, in particular human hair, in which, using a delivery apparatus, an agent in accordance with the first subject agents contemplated herein is foamed into a foam and the resulting foam is applied onto the keratin-containing fibers.

It is preferred that a shape be imparted to the keratin-containing fibers, and that that shape be fixed in place by the agent of the first subject described above.

The delivery apparatuses recited earlier (see above) are considered preferred.

A fourth subject of the agents contemplated herein is a method for treating keratin-containing fibers, in particular human hair, in which, using a delivery apparatus, an agent in accordance with the first subject of the of agents described above is applied as a spray onto the keratin-containing fibers.

It is preferred that a shape be imparted to the keratin-containing fibers, and that that shape be fixed in place by the agent of the first subject of the agents described above.

The delivery apparatuses recited earlier (see above) are considered preferred for the foregoing embodiments of the agents described herein.

EXAMPLES

Unless otherwise noted, the following quantity indications are understood to be percentages by weight.

The following formulas were prepared by mixing the raw materials indicated:

Raw materials E1 V1 V2 2-Amino-2-methylpropan-1-ol 0.12 — 0.24 Aquastyle ® 300 ¹ 2.50 5.00 — Acudyne LT 120 ² 1.60 — 3.20 Water <-------------- to 100 --------------> ¹ INCI nomenclature: Polyquaternium-69 (30 wt % active substance in ethanol/water mixture, molecular weight 350,000) (Ashland) ² INCI nomenclature: Acrylates/C1-2 Succinates/Hydroxyacrylates Copolymer; 47 wt % active substance in water (DOW).

Standardized hair strands of the Kerling company (item no. 827560), hair type “European Natural,” color 6/0, with a length (L_(max)) of 220 mm and a weight of 0.6 g, were used.

For preparation, the strands were washed with 12.5-wt % sodium laureth sulfate solution. The hair strands were dried overnight in a drying oven at 318 K.

0.18 g of the compositions was respectively applied onto each hair strand and massaged in. The strands were then wound onto a curler (Fripac-medis, diam. 7 mm, item no. D-1203) and dried overnight at room temperature.

The curlers were then carefully removed, and the strands were suspended. The length of each of the curls was measured (L₀), and the strands were put into a climate chamber. They were stored there at 294 K and a relative humidity of 85% for a period of 24 h, and the lengths of the curls were then measured again (L_(t)).

Five test strands were correspondingly treated and measured for each composition.

High humidity curl retention (HHCR) was calculated using the formula below, and the arithmetic mean of HHCR values for the five test strands was obtained for each composition:

${HHCR} = \frac{L_{\max} - L_{t}}{L_{\max} - L_{0}}$ HHCR E1: 92% HHCR V1: 82% HHCR V2: 21%

The polymer combination of agent E1 (total of 1.5 wt % polymer active substance) exhibits a significantly higher HHCR than the same quantity of polymer (1.5 wt % active substance) of the respective individual polymer of the comparison compositions V1 and V2.
